Tomato Genotypes

To increase productivity in tomato, it is necessary to develop superior varieties/hybrids. This is, in part, dependent on variability in the genetic material which affects agro-morphological and biochemical characters in crop breeding. A study was conducted with 51 tomato genotypes and the standard checks/reference cultivars Punjab Upma, Punjab Chuhhara and Punjab Ratta to determine character association, path coefficient analysis and genetic diversity to select genotypes and traits for breeding. There were differences among genotypes for all characters indicating a high degree of variability in the material. Overall, highly significant, positive, correlation coefficients, as well as high direct effects of fruit weight and marketable yield on total fruit yield, indicated these traits are reliable components for selecting high fruit yielding tomato genotypes. The D2 statistics confirmed the highest inter-cluster distance between clusters VI and VIII (27638.44). Maximum similarity was observed in clusters IV and VI (191.02). This indicated existence of the possibility to improve genotypes through hybridization from any pair of clusters and subsequent selection can be made from segregant generations.

Effect On Yield

Correlations and path coefficient were studied in 39 exotic tomato (Solanum lycopersicum L.) genotypes for nine yield contributing characters. The correlation coefficients were determined to find out the inter relationship among the characters studied. Yield per plant was found highly significant and positively correlated with flowers per plant, fruits per plant, fruit length, fruit diameter and individual fruit weight which indicated that yield could be increased by improving a traits. In order to obtain a clear picture of the inter relationship between yield per plant and its components, direct and indirect effects were measured using path coefficient analysis. Fruits per plant showed the highest positive direct effect (0.980) on yield per plant followed by individual fruit weight (0.958). On the other hand, the highest negative direct effect on yield per plant showed by days to first flowering (-0.277) followed by fruit length (-0.141). The characters showed high direct effect on yield per plant indicated that direct selection for these traits might be effective and there is a possibility of improving yield per plant through selection based on these characters. Residual effect was considerably low (0.183) which indicated that characters included in this study explained almost all variability towards yield.

Abstract. Sahid ZD, Syukur M, Maharijaya A. 2020. Genetic diversity of capsaicin content, quantitative, and yield component in chili (Capsicum annuum) and their F1 hybrid. Biodiversitas 21: 2251-2257. Chili (Capsicum annuum L.) is one of the horticultural plants that have many benefits. The benefit of chili was determined by pungency level of its fruit. Pungency level of the chili is due to the capsaicin content in fruit. Information about the genetic diversity of capsaicin is still rarely available. The aims of this study were to obtain diversity information on quantitative, yield component, and capsaicin content, and to analyze the correlation among chili genotypes based on their morphological characters. This study used Randomized Complete Block Design with three replications. The genetic material used in this study consisted of 21 genotypes consisting of 6 genotypes of chili elders and 15 hybrid F1 genotypes resulting from their crossing. Six genotypes of the chili parents are C5, F6074, F9160291, Yuni, Bara, and Giant. 15 hybrid F1 genotypes used in this study are C5 x Bara, C5 x F6074, C5 x Yuni, C5 x Giant, C5 x F9160291, Bara x F6074, Bara x Yuni, Bara x Giant, Bara x F9160291, F6074 x Yuni, F6074 x Giant, F6074 x F9160291, Yuni x Giant, Yuni x F9160291, and Giant x F9160291. The observation was made on the variables of quantitative, yield, and capsaicin components on chili. The results showed that the highest capsaicin content only was found in Bara x F9160291. The results of scatterplot analysis showed that the highest capsaicin and yield component was found in BaraxF6074 and C5 x Yuni genotype. The results of cluster analysis showed that chili was clustered into three color groups. The character of capsaicin content is negatively correlated and very different from fruit weight, fruit diameter, fruit length, thick fruit flesh, total amount of fruit per plant, and fruit weight per plant.

Integration of inorganic and organic fertilizer is a very important tool for sustainable production of tomatoes contributing to human health. There were six treatments followed the design of RCBD with three replications to observe the growth, yield and the nutritional quality like lycopene and β-carotene of tomato. Treatments were; F1: Control, F2: Pond sediments-100%, F3:50%F2+50%F6, F4:50% F2+50%F5, F5: soil test based (STB) nitrogen as urea, and F6: vermicompost-100%. Statistically significant variations were found for the plant growth and yield. The highest growth and yield performances were found from the treatment F4. Fruit clusters, fruit numbers and fruit weight per plant were found highest in the treatment F4, whereas the lowest was found in the control. The highest marketable yield of tomato (96.17 t/ha) was obtained from the treatment F4 which was 20%, 29%, 13%, and 41% higher compared to F5, F2, F6, and F1 treatments, respectively. The highest amount of lycopene (67.31 ppm) and β-carotene (53.52 ppm) were found from F4 and F6, respectively, whereas the lowest amount was 42.59 ppm lycopene and 13.85 ppm β-carotene from F5 and F1, respectively. Inorganic and organic fertilizer like pond sediments can be applied for the sustainable production of tomato with friendly environment.

Experiments were carried out to evaluate two salts, K2SO4 and NaCl, as materials to supplement the electrical conductivity (EC) of the basic nutrient solution in nutrient film technique (NFT). The effects of these materials on the growth, yield and fruit quality of greenhouse tomato (Lycopersicon esculentum Mill.) grown by NFT were quantified. These effects were tested by increasing the recirculating solution EC from a base value of 1500 μS·cm-1 to that suitable for the crop growth stage with normal feed (macronutrients), 0.38 m (0.53 lb/gal) K2SO4 or 1.14 m (0.55 lb/gal) NaCl, at a common pH of 6.2. In 1995 and 1996, there were no significant effects of the treatments on crop growth. In 1995, the early marketable yield was significantly lower when K2SO4 was used but the yield at the end of the season did not differ among the treatments. Furthermore, with K2SO4, the proportion of grade #1 fruit in early total yield was lower than in the control, while, fruit biomass content was higher than in the NaCl treatment. In 1996, the cumulative marketable fruit weight was unaffected by the treatments. A trend toward high number of large grade fruit occurred with the NaCl treatment. The pH and EC of the fruit homogenate were favorably affected by the NaCl treatment. Adding K2SO4 or NaCl in partial substitution of macronutrients in the recirculating solution may have a role in NFT systems in not only reducing environmental pollution (from nitrates and phosphates) and fertilizer costs, but also in improving fruit quality and, therefore, profit margins.

Genetic variability, heritability and genetic advance for fifteen yield contributing traits were studied in F2 population obtained from the cross of Arka Vikas × EC 519809. The study indicated that existence of considerable amount of genetic variability for all the characters studied. The characters viz., fruit yield per plant, number of fruits per plant, number of primary branches, total phenol and pericarp thickness exhibited higher values of genotypic and phenotypic coefficient of variation. Whereas, fruit yield per plant, individual fruit weight, pericarp thickness and number of primary branches per plant exhibited high estimates of heritability and genetic advance for yield per plant and average fruit weight. These characters can be effectively improved through selection. Correlation indicated that yield was significantly and positively associated with plant height, number of flowers per cluster, percent fruit set, fruit length, fruit diameter, individual fruit weight and number of fruits per plant. Number of fruits per cluster and number of fruits per plant showed the highest positive direct effect on fruit yield per plant. Direct selection may be executed considering these traits as the main selection criteria to reduce indirect effect of other characters during development of high yielding tomato variety.

Twenty parental genotypes of tomato were planted and observed of yield and yield attributing traits to measure genetic variability, character association and path coefficient analysis. Parent TM 371 ranked first with respect to yield (4.73 kg fruit yield per plant) followed by TM 390. In terms of average fruit weight TM 390 also was better performer. Analysis of variance for each trait showed significant differences among the genotypes. High genotypic and phenotypic coefficients of variation were recorded for fruits per plant, locule number per fruit and fruit yield per plant. Heritability was observed high for flowers per cluster, fruits per plant, fruit weight and fruit length. fruit per plant (52.30), followed by fruit weight (46.32).High heritability associated with high genetic advance was observed for fruits per plant (52.30) and fruit weight (46.32) and flower per cluster (33.50). Selection for such traits might be effective for the fruit yield improvement of tomato. Significant positive genotypic and phenotypic correlation was observed of fruits per plant, fruit weight, fruit diameter and locule number per fruit with fruit yield per plant indicated that selection strategies must be focus on these traits. Fruit diameter showed the highest positive direct effect (3.25) on fruit yield per plant followed by fruits per plant (1.54). Direct selection may be executed considering these traits as the main selection criteria to reduce indirect effect of the other characters during the development of high yielding tomato variety.J.

A study of the yield structure of nine potato genotypes was carried out over a 3-yr period in irrigated and dryland environments in the Prairies. This was undertaken to develop an understanding of yield component interactions, which could be useful in the selection for yield in early clonal generations of the Prairie Potato Breeding Project. Path coefficient analysis was used to partition correlation coefficients among yield and yield components into direct and indirect effects. Marketable yield of tubers in the irrigated and dryland environments differed markedly as did interactions between components in determining yield. Mainstem and tuber number were associated positively with yield under irrigated but not under dryland conditions. Tuber yield was strongly associated with average tuber weight under both irrigated and dryland conditions. The study indicates that consideration of yield component interactions in early generation selection "activities" could assist in the identification of high-yielding genotypes.
